WINDOW.

Application filed April 10, 1916.

To all whom it may concern:

Be it known that I, Gnoncn A. FAIR, a citizen of the United States, andresiding at Detroit, in the county of lVayne and State of Michigan, haveinvented a new and Improved Window, of which the following is aspecification.

The present invention has reference to a window, and its object is toprovide a structure wherein the sashes each include a plurality of panesbetween which dead air spaces are formed whereby the interchange of heatbetween the interior and the exterior of the building is retarded, toprovide means whereby the sashes are not only slidable vertically inrespect to the frame but may have their panes swung inwardly to allowcleaning from the inside of the building, to provide means whereby thesashes may be removed from a casement by which they are carried bya'movement substantially in the plane of the casement, to provideimproved ventilating means coopcrating with the sashes whereby therenewal of air in the building is properly regulated at top and bottomof the window and whereby insects are excluded, to provide an awn inghood cooperating with the ventilating means at the top of the window forexcluding rain and for concealing and protecting the awning, to providea second hood located at the bottom of the window for excluding rain,and to provide awning controlling means operable from the interior ofthe building.

One embodiment of the invention is illustrated in the accompanyingdrawings, which are, however, to be understood as diagrammatic ratherthan restrictive, since the ac tual details of construction may bemodified in some particulars within wide limits.

Figure 1 is an inside elevation of the window, parts being broken away.Fig. 2 is a vertical section, the window being closed. Fig. 3 is ahorizontal section on the broken line 33 of Fig. 2; the manner in whichthe sashes and panes may be swung inwardly is indicated in dashed lines.Fig. 4 is a horizontal section on an enlarged scale through the rightside of Fig. 3, the parts being sectional and separated to show thelines upon which relative movement may take place. Fig. 5 is an enlargedhorizontal section taken through the opposite side of the window. Fig. 6is a vertical section through the window (the sashes being re-Specification of Letters Patent.

moved) showing the stile of the casement remote from the pivots, withthe removable sectionwithdrawn, whereby an opening is formed throughwhich the sashes may be drawn out edgewise from the casement. Fig. 7 isa side view of the removable section of the casement stile.

Similar reference characters refer to like parts throughout the severalviews.

In the embodiment shown, 1 indicates the wall which is provided on oneside of the window opening with anchor plates 2 and 3 to which issecured the fixed side member at, preferably sheet metal, of the frame.A similar side member 5 is located on the opposite side of the openingbut it will be observed that, in this instance, the inturned flange 6 ofthe anchor plate 2 is spaced slightly from the edge of the flange 8 onthe side member 5. At the top and bottom (Figs. 2 and 3) the fixed framemaybe formed of I sections 10 having their outer flanges 11 extendingupwardly and downwardly, respectively, into the window opening.

Mounted to swing horizontally on hinges 12 carried by the side member 4;is a casement, the adjacent stile of which may include an inner face orsash guide plate 13, an. outer face or sash guide plate 14, a connectingchannel plate 15 and a plate 16 to which the hinge is preferablyattached by screws 17. The several plates named are spot welded orotherwise rigidly secured together, and the plate 15 also has rigidlysecured thereto a sash guide 18, preferably of channel section, havingflanges l9 and 20 extending out into the window opening,

and to the flange 20 a sash guide plate 21' is welded orotherwise'attached. The opposite stile of the easement frame (Figs. 3and 4) may be formed of a substantially l shaped section 22 (the outerflange 23 of which forms a face or sash guide plate and the inner flangeof which has a face or sash guide plate 24 secured thereto) and achannel sash guide plate 25 rigid therewith,

to the inner flange 25 of which'a combined guide and stop plate 25 issecured in alinement with the plate 21. Thus the stiles include pairs ofchannels in which sashes may be guided in vertical sliding movement. Itwill also be seen that the section 22 has a rib 26 that isreceived'between the flangefi of the anchor plate and the flange 8 ofthe frame member 5, whereby a tight joint is 'retain the easementclosed.

formed when the casement is closed-on the opposite side an angle iron 27is secured to the plate 14 and engagesthe flange, on the anchor plateQ'for a similar purpose. Spring latches 28 (Figs. 1 and 3) have boltsthat are projected into holes in the member 5 to The top rail "ofthecasement is' preferably formed of a channel section 80. and an angleiron 31 spaced slightly from the inner face of theouter flange 32thereof. The lower rail is. a box-like,stnucture having a top plate. 35and a compound bottom plate 36-3T1 having short, upturned, slightlyspacedflanges 38-39 on its inner edge, whereas its outer edge is turnedupwardly some distance, as. indicated at 410, but is however spaced fromthe outer edge otthe top platefiatoform a tree opening 4.2. Sincetheinner edge ofthe top plate is also spaced from th flanges 38-89, it willbe V seen that a passage 15 formed throughwhich cold; air may enter thebuilding when the lowersash is raised; Theventilatmg features i will,however, be more. fully described later.

Tlie means forforming the outer channel in the main easement on the.side thereof next-tothe pivots, .12 may include a stifl'e'ner or fillerplate :45. Arranged to slide vertically in. the guide channelsot theeasement frame are-an upper; sash and a lower sash; the formerpreferably includes a stile on. the side adjacent the pivots-12 which isformed of a main sash element 48 of substantially channel cross-section,said element having anouter flangeftG, in alinement with the flange 19ofthe guide 18 and an inner flange sash being received between theflange 58 and. plate 25 on the guide member 25,

whereas the flanges of the inner sash lie between-the plate25 and theplate 24:. As best shownin Fig. 2, the'upp'er rail 63 of the. uppersash. is'of channel cross section, the' outer flange tit being ofconsiderable depth and. being received, when the window is closed;between themembers 31 and 32. The lower rail 66 of thelower'sash, in asomea what. similar way, has its inner flange 68 extended? andreceived:- between the; flanges 38 1 and 39 and may be groovedhorizontally at. 694' toiform a hand hold wherebythe sashes mayt-beraisedbr lowered. The meeting; rails of the sashes are reversely ar-'ranged channel irons-71 and may be proshown). It will be observed thatthesashes counterbalance. one another by means of the cord 72 thatpasses over a pulley 73 suspended ifrom the top rail oi 'the casement bya spring 74. 7

ldounted on vertical pivots 78 carried by the sash stiles (preferably onthe stiles adjacent to the-pivots 12) are outer pane casements 79 inwhich are carried the outer glass panes 80. The stiles of thesecasements remote from the pivots 7 8 are in each instance provided withthe reversely arranged outer and inner flanges 81 and 82, the former,when said easements are closed, abutting the plate 23 or the plate 25and the'latter engaging the wall 83 of a reentrant corner 84 on thecorresponding member 55 to form tight joints; on the pivot side, theeasements fit snugly against the plates 14 and 21 of the sash stiles fora like purpose. The outer easements in turn have vertical pivots 85 onwhich inner pane casements '86- may swing, the last mentioned easementsbeing provided with sealing flanges 88 adapted to be received in thereentrant corner grooves 89 r'orinedin the outer pane casements. Variousmeans may be employed for retaining the pane casements in closedposition, that shown being buttons '90 carriednby the outer panecasements and havingtwo arms 91 and 92 which engage with the walls ofthe reentrant corners'84 and the flanges 88. in an obvious manner. a

v A portion 89 of the member 22 of a length somewhat greater than theheight of the sashes (Fig, .6) is secured to the remainder of the memberby screws, not shown, and may be detached therefrom. It'will be noticedthat the pivots 78 and 85 otthe lower sash are forward of the rear facesof the plate 24-thus when the main casement is swung inwardly on pivots12 and the portion 89 is removed, the cord 72 may be disconnected andthe .sashes brought to the proper level' after which they may bewithdrawnby a movement edgewise through the stile. -By similarlylocating the pivots for the upper sash with reference to the plate 21,interference of one sash with the other in the vertical slidingmovements is avoided.

If desired, the main casement may have pivot'means 95 upon which a shadeor ourtain box 96 is mounted to'swing horizontally; the'pivot; meansisalso preferably of such nature as to allow the box to be readilydetachedkey hole slots 98 and screws 99 (Fig. 1) may be employedfforthelatter purpose. Any suitable latch 100 retains the otherfend of thebox; in position A shade 102is sup-portedjinthe. box and may be guidedin thin channel strips 103 on the casement. a

Referring again to the. ventilating tea vided with any suitable sealingstrip (not w tures, it will be seen that the frame includes at the top adepending plate 105 and a horizontal cross-piece 106 about at the levelof the upper portion of the casements of the upper sash when the latteris raised, and that the intervening space is closed by a screen 107. Theflange 32 of the main casement and a cross-piece, 108 with which thecasement may also be provided overlap the edges of the screen when thecasement is closed. Thus when the upper sash is lowered air may passthrough the opening. The passage of air through the box-like lower railof the main casement is controlled when the window is raised by thefollowing mechanism :110 designates a deflector plate, preferably abouta quadrant of a cylinder, having end sectors 111 connected to the maincasement by horizontal pivots 112; this plate is retained within therail when the window is closed by a spring catch 113 that engages a lug11st thereon, but may be swung inwardly to the dash line position (Fig.2) when the window is raised, and is then retained in the position lastnamed by the engagement of a lug 115 with a spring catch 116 on theplate 87. The radial face of the deflector which is uppermost when thelatter is in dashed line position is provided with a slide or closure118 that preferably has a small opening 119 therethrough, which bothaffords a grip for the fingers in withdrawing the deflector from therail and in moving the slide to and from the dashed line position,whereby the free opening through the air passage is regulated. A screen120 is arranged across the deflector adjacent to the closure.

In order to prevent rain from beating through the screen. 107 and theopening 412, hoods 125 and 126 are attached to the fixed fran'ie in anysuitable way. These hoods are preferably connected by angle irons 128.An awning roll 129 having spring return mechanism of ordinaryconstruction (not shown) is mounted in and concealed by theupper hood,and the awning 130 may be drawn down across the window opening by meansof a cord 131 which passes around a guide pulley 132 carried by asupport 133 of channel shaped cross-section which is attached to thelower rail of the main casement. From the pulley 132 the cord passesinwardly to a point in proximity to the inner face of the easement railwhere it may be secured in any suitable way, for example, to the cleat133. Thus the awning may be adjusted without reaching out of the window.

If desired, the wall may be recessed beneath the plate 10 to receiveheating units 134 (Fig. 2), in which event the plate will be providedwith proper openings 134 to allow the escape of heated air.

Should it be desired to clean the outer surface of the inner pane ofglass, the latter may be swung inwardly on the pivots 85, which alsoaffords access to the inner surface of the corresponding outer pane;likewise, the outer pane casement together with the inner casement maybe swung inwardly on pivots 78 to allow the outer surface of the outerpane to be washed. Or if a large free window opening is desired for anypurpose, the main casement may be swung inwardly on pivots 12.

The details of construction may obviously be changed within wide limitswithout departing from the spirit of the invention; I do not, therefore,wish to be limited other wise than as indicated by the subjoined claim.

I claim A window construction comprising a frame, a vertically slidahlesash supported thereby, an outer glazed casement mounted on said sashand swingable inwardly in re spect thereto about a vertical axis, and aninner glazed casement mounted on the outer glazed casement and swingableinwardly in respect thereto about a vertical axis, whereby an air spaceis formed between the glazings when the easements are closed and wherebythe glazing may be presented in desirable position for cleaning.
